FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 707,715, dated August26, 1902. Application filed June 9,1902. Serial No. 110,827. (No model.)

To (1, whom it may concern.-

Be it known that I, SIMON B. PARKER, a citizen of the United States,residing at Springfield, in the county of Springfield and State ofMassachusetts, have invented certain new and useful Improvements inFire-Escapes; and I do hereby declare that the following is a full,clear, and exact description of the same,

reference being had to the annexed drawings, making a part of thisspecification, and to the letters of reference marked thereon.

The present invention has relation to that class of fire-escapescomprising a series of links or rings suitably hinged together to form arope or device by which the person may descend from a building or otherstructure.

The invention consists in a series of links or rings suitably hingedtogether to form a flexible rope or cable, said links or rings havingsuitable means to prevent the same moving laterally or sliding upon eachother, as will be hereinafter described and claimed.

Figure 1 of the drawings is a front elevation of flexible rope or cableconstructed substantially in accordance with my invention; Fig. 2, adetail view of one of the links or rings.

In the accompanying drawings, A represents a series of links or rings,which are constructed of wire of suitable thickness and strength andwhen connected together form a flexible cable or rope or other means bywhich a person may conveniently descend from a building or otherstructure. These links or rings are preferably provided with shanks Band hooks or other means by which the links or rings may be hingedtogether. In the present instance I have shown the shank B of wiretwisted upon itself, the ends of the wire forming the shank terminatingin hooks O as a means of loosely connecting one link or ring with theother; but any other suitable means may be provided for joining thelinks or rings together. The upper one of the links or rings is providedwith a hanger D, of any suitable construction, by which the cable orrope formed by the series of links or rings may be conveniently engagedwith a window-sill or other parts of a building or similar structure.Any convenient means may be provided for attaching the end of the cableor rope to the stationary object from and to prevent this is theessential feature of the invention. To attain this end, I provide thering with suitable means that will form a stop, such as a lug orprojection, as indicated at E and shown more clearly in Fig. 2 of thedrawings. This stop E is suitably formed on the link or ring at theupper portion, and any means may be employed that serves the purpose ofpreventing the adjacent ring from sliding late rally thereon, therebyholding the series of links or rings in a true line with each other whenany weight is placed thereon and prevent them from moving or swayinglaterally independent of the other, the upper one of the links or ringsnot requiring this stop.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. A fire-escape consisting of a flexible wire cable or rope comprisinga series of links loosely connected together, and suitable means uponthe upper ends of said links whereby one link is held against laterallysliding upon the adjacent link to which it is connected, substantiallyas and for the purpose set forth.

2. A fire-escape consisting of a flexible wire cable or rope, comprisinga series of loose1yjointed links, and stops upon the upper ends of thelinks to hold the same against laterally sliding upon each other,substantially as and for the purpose described.

3. A fire-escape consisting of a flexible wire cable or rope comprisinga series of links provided with shanks having means for engaging theshanks with the adjacent links, and stops upon the upper ends of thelinks to hold the same against sliding laterally upon each other,substantially as and for the purpose specified.
